Radeon lockup on 3.8.5-201.fc18.x86_64

Every day or so, I'll click something and my screens go blank for a
second or two.  dmesg complains about a lockup, and afterwards
everything is painfully slow.  (Even switching focus to other emacs
windows takes a second or two.)  Once this happens, if I restart X, I
get a blank screen, although the mouse still works and I can switch
VTs and use the console.

My userspace driver is
xorg-x11-drv-ati-7.0.0-0.9.20121015gitbd9e2c064.fc18.src.rpm.  I have
Option "ColorTiling2D" "true", but I'm not sure this matters.
